Here go again I want to understand right this exercise, please help: Suppose that in this economy all the funds for capital come from savings by the 10 individuals. Firms' demand for capital is given byQD=100100r.

Questions:

What is the market supply for funds if the interest rate is 30%?

Qs=?

What is the market supply for funds if the interest rate is 70%?

Qs=?

What is the equilibrium interest rate that clears the capital market?

QD=Qs

100-100r=100r

100=200r

r=0.5

What is aggregate consumption in each period at that interest rate? C1 and C2?

QD=C1=100-100(0.5)

C1=50

C2=50*(1+0.5)

C2=75

So please help me what is the procedure to obtain Qs when r=30% and r=70%. Many thanks.
